[0002] Cooling fans are mainly used for cooling and capacity expansion of dry-type transformers and cooling and reducing the temperature of electronic equipment, distribution cabinets, high and low voltage switch cabinets and other products. The cooling fan motor is a device in the cooling system to remove heat and set them into the atmosphere.

[0003] Publication number "CN208950981U" provides a fan protection cover, in which the first fixed pin shaft passes through the arc-shaped sub-cover plate and the arc-shaped main cover plate in sequence, so that the arc-shaped sub-cover plate can rotate with the first fixed pin shaft as the center axis. After the arc-shaped sub-cover plate is rotated into the sub-cover plate groove, the arc-shaped sub-cover plate can be conveniently cleaned, and the arc-shaped sub-cover plates at different positions can be flipped over separately and cleaned separately; according to different needs, the fan-shaped filter net can be rotated, and the four fan-shaped filter nets can be adjusted to overlap with each other, or the four fan-shaped filter nets can be made not to overlap with each other, so that the inner circle of the annular retaining ring can be blocked.

[0004] However, the above technical solutions and the prior art have the following defects:

At this time, the first protective mesh 3 and the second protective mesh 6 can be disassembled and cleaned. After cleaning, the first protective mesh 3 and the second protective mesh 6 are respectively mounted on the front and rear ends of the cooling fan body 4. At this time, the external threaded rods 56 on the upper and lower sides are rotated forward respectively, so that the strip plates 55 on the upper and lower sides can drive the locking blocks 58 on the upper and lower sides to move outward and be mounted in the locking grooves 571, so as to lock the first plug block 54 and the second plug block 57 again, and finally tighten the locking screws 52 on the upper and lower sides respectively.
